Football Video Support (FVS) has been trialled for the past two years. It is intended for use in leagues which have fewer cameras and officials.

There is no actual VAR, only a replay operator presenting the match referee with camera angles at the pitchside monitor.

Each coach gets two challenges per match. If a challenge is successful, the manage keeps it.

Football Association chief executive Mark Bullingham said earlier this year that FVS “reduces the amount of times when there is a VAR intervention and effectively puts the onus on the coach”.

But it is not quite that simple.

While FVS does mean fewer checks, it is likely the game would stopped more often.

In the last two rounds of Premier League games, the referee went to the monitor just twice across the 20 games.

With FVS that could rise to four times per game – and potentially more if a coach has a challenge upheld.

Trials have been taking place in the third division of the men’s game and the top flight of the women’s game in Spain, and in Serie C in Italy.

It was expanded to the Canadian Premier League this month, but already there have been concerns about how it is used.

Pacific FC and Supra du Quebec were locked at 2-2 in injury time when the referee allowed a tackle by the home side’s Joshua Belluz to go unpunished.

Supra du Quebec lodged a challenge for a straight red card to Belluz.

It was not a red-card foul but once at the monitor the referee had to take the correct disciplinary action. That was a yellow card and, as Belluz was already on a caution, he was dismissed.

Supra du Quebec lost their challenge, but they had used it tactically to get a player sent off. They then scored a winning goal in the added time caused by the review.
